We've already described the major security benefits of securing your Firefox saved passwords, but you're not perfect, and you may from time to time wander away from your computer after you've entered your master password, leaving your saved logins at some sneaky turd's sticky fingertips. With Master Password Timeout installed, your master password will timeout after you're away for a bit so an intruder would need to log back into the master password to access your logins. This smart extension is a must-have for anyone who uses the master password feature. Master Password Timeout is free to download, works wherever Firefox does. Thanks Henry!
